Nokia Lumia 900 or iPhone 3GS?

I asked a question on Twitter a little while ago, and wanted to get an even bigger idea of what everyone thinks. This is a serious question — would you choose an iPhone 3GS over the Nokia Lumia 900? You can get iOS 5, a decent camera, HD video recording, iMessage, the App Store, iTunes, and of course, everything else you’d get with an iPhone. On the Lumia 900, you have a larger and much better display, 4G LTE, and a clean and sophisticated OS.
